Background & Objectives: Cardiovascular events are among the most common causes of mortality in patients with end stage renal disease. Caediac biomarkers such as troponins are very sensitive in diagnosing heart problems. Troponin I can be used to diagnose acute cardiovascular problems in hemodialysis patients.

 Methods: In this descriptive-analytical and cross-sectional study the level of troponin I was measured in 39 hemodialysis patients using ELISA method and BUN, Cr and Hb level before hemodialysis. LVH and LVMI were determined by echocardiography. The data were analyzed using SPSS.

 Results: The patients were 52.92 years old on average. 26 patients were male and 13 female. The average of tropnin I was 0.78 μ g/l. There was no meaningful relationship between troponin I and LV MI, age and sex. However, a significant relationship was found between the level of troponin I with EF and diastolic dysfunction (p=0.05).

 Conclusion: Troponin I can be regarded as an indicator of LV dysfunction.
